You can also set a timeout, for example --timeout 120 (120 seconds).  It
will report on the files that timed out and you can check on them
manually.  Some other useful options are:

--profile: see how long it spends in each rule or various parts of the
OCaml code

--show-trying: see what function it is working on

--debug see what rule and with what inputs it is working on

It may work better to put --debug before the others.
